I just built a new PC with Vista and so far everything is great except that I can't get the drivers for my X-fi XtremeAudio(moved over from my last PC where it worked great) to install. Everytime I try to install them, it says that it can't find a supported device. However, in my device manager, there is an unknown multimedia audio device installed in the PCI slot. Does anyone have any ideas how I could fix this?
